manufacture, and `hicn may be easily and cheaply attached to a magneto of the rotary type, thereby permitting same to be equipped with actuating springs to operate as an oscillator.

Another object is to provide a spring arm forv magnetos, made from stamped and formed sheet metal.

A further object is -to provide an oscillating magnete or few parts and one in which the spring arms also serve to clamp the magnets and tcp plate of the machine in place.

My invention may be used in connection with any magneto having a projecting shaft be coimected to a shuttle wound armature or to any movable part, whereby the machine is operated.

Figure l is a view in perspective, illusu trating my invention in'use on a magneto. Fig. 2, a vievi7 of the formed sprinff arm constituting the invention.

.iilre gures denote the same parts wherever they are shown.

l denotes a magneto, the shaft of which is shown at 2. Moimted upon this shaft is 'the trip ,lever 3, to which is connected the springs i and 5. The outer ends of these springs are carried on suitable pins, shown at 6 and 6,'which are fastened in the ends 7 and 7 of the spring arms 8 and 8. These arms are clamped to the neto by means of screws, one of which is shown at 9, passing through or between the magnets or the magneto, and entering the pole pieces of same.

lt will be noted that the magneto may have a suitable framework of any Well usually consisting of the which known type, this lbase on which the magnetorests, to

sides of the magf is attached pole pieces (not shown). Across the top ot these pole pieces is the top .plate l5. The top plate, base, and pole pieces, comprise the framework of the magneto adapted to support the magnets, and to which the spring arms 8 and 8 are attached as just described. As the construction of such a farmework is readily understood I do notdescribe the same in' detail.

The spring arms 8 and 8 have projecting lugs l() and 10', which fit over the top plate of the magneto and hold same in place. A corresponding but shorter projecting portion 13 serves to locate each arm vertically, in relation to the opening 14 between the magnets.

Fig. 2 struction of the spring arms whereby the posits 6 and G for supporting the springs are eliminated, their place being taken by the outwardly turned ends 11 formed integral with the spring arm, and provided with groove 11 for supporting the spring.

From the foregoing it will be seen that the spring arms 8 and 8 not only support the springs connected to the armature trip lever, but also clamp the top plate in place, and also clamp the magnets to the pole pieces. It is also evident that these spring .Irms may be attached to an ordinary rotary magnetmthereby making same an oscillator without removing the armature, or in any other Way disturbing the assembly of the parts, these arms being inthe nature. of an at- This is a great saving to those using both the rotary and oscillating types of magnetos, as they are not obliged to stock two kinds of magnetos as would otherwise be the case.

l am aware that niagn'etosV with spring arms are in common use, but such arrangements have the spring arms as part of the end plate 1Q of the magneto; or where the arms are attached to the sidcsof the magneto they are bolted to the edges of the end plates, and inno case do these arms form an attachment for a rotary magneto arranged to be put on same at any time after its construction and use as a rotary machine. Nor do the arms on any such machines serve to hold on the top plate of same, thereby eliminating screws o'r other devices for this purpose, nor do they serve to clamp the inagnets to the pole pecesggoi the shows an alternate form of con? o Ze Having thus described my invention, claim:
